Patent NO-146765-C (NO)
Inventor: MOHLA PREM P
IPC: C21C1/10
Filed: 1976-11-09
Abstract: A method of making a more economical and reliable treating agent for use in late metal treatment when pouring metal castings. The treating agent is defined as an essentially homogeneous solid cast block preferably containing alloying ingredients to nodulize or inoculant ferrous metal. Each block is designed to present a generally uniform reaction surface to molten metal to be treated. This is obtained by casting the block to a shape which snugly fits a prepared basin in the mold gating system over which the molten metal to be treated must flow, or to cast the block in an annular configuration through which the molten metal must flow. The latter block has contoured inner surfaces which maintain a generally constant reactive surface as the block is consumed. These blocks are preferably prepared by simultaneously casting a large number in closely nested relation. Each mold for said blocks receives molten material, out of which the agent is formed, from a common sprue; runners interconnect the mold cavities and sprue, for example, in a simulated "Christmas tree" arrangement. The gating system and mold cavity pattern, for casting the treating agent to a special shape are all comprised of a material that will vaporize upon contact by the molten treating agent, such as polystyrene. The unitary tree structure of foam patterns and gating system is placed in a flask and surrounded by unbonded heat absorbing particles, such as sand or steel shot. Rapid solidification is assured by the selection of heat absorbing particles and by the use of the vaporizable patterns to avoid noticeable segregation in the alloy blocks. The blocks formed for the treating agent are characterized by increased homogeneity, absence of undesirable segregation, absence of internal oxidation, and absence of organic or refractory impurities; the blocks are less costly to make both as to capital requirements and operating expenses.

Abstract: A power capacitor and method of making it employs the technique of stacking capacitor sections together in an enclosure of which each section includes rolled electrode foils and dielectric layers of which at least one of the electrodes has a rolled edge resulting in a greater thickness in that portion of the section. In order to permit thorough impregnation of the section, the winding tension is deliberately made loose and the initially resulting section is insufficiently tight to retain conductive tabs reliably in contact with the foil electrodes. The stacked sections have, however, between them in the body portion intermediate the rolled edges, one or more sheets of material that compress the body portion and insure reliable pressure contact thereat while not interfering with the impregnation of the fluid throughout the section.

Inventor: LAROCHE JR EVANS ALLEN
IPC: C04B35/65
Filed: 1988-01-05
Abstract: A method of producing shaped, self-supporting ceramic bodies includes preparing a mold by applying a permeable, conformable material (5) to a shape-defining surface (3) of an expendable pattern (2). The permeable, conformable material, when set or stable, provides a mold with a shaped surface which is defined by, and is therefore substantially congruent to, the shape-defining surface. Upon heating, the material of the expendable pattern (2) combusts or volatilizes and thus establishes the shaped cavity mold. A molten parent metal (1) is then vaporized with a vapor-phase oxidant in such a manner as to form a ceramic body which grows into the mold cavity, and is shaped by it. The ceramic body is recovered from the mold having a shaped surface replicating the shape-defining surface (3) of the expendable pattern (2).

Granted: 1995-02-28
Abstract: The present inventions is directed to a bed mattress, in which a mattress body  (1)  is  formed with  a  core  portion consisting of a hard molded foam  having a sufficient thick-ness or hollow synthetic resin moldings having a rigidity, and elastic  surface layers  (6),   (7)  including protecting plates (4),   (5) overlayed on both sides of the core portion (3) sandwiched therebetween.  At least one of the surface layers  (6),   (7) is formed by overlapping a first cushion layer  (10)  consisting of  a soft cushion material,   and a second cushion layer  (11)  consisting or a semihard cushion material having a depression-and-protrusion surface  (13) on its surface on the protecting plate 4.    In a conventional bed mattress,   since a plurality of coil springs fixed to a metal frame is incorporated,  a gross weight becomes heavier and handling is inconvenient.  In this invention,  however, since the metal member is not used and a hard molded foam and hollow synthetic resin moldings having a rigidity are used as a core portion (3),  it is light and there is no problem of rusting and breaking.  Besides,  since the  depression-and-protrusion  surface  (13)  of  the  second cushion layer (11) on the surface layer supports the body in point contact,  a good permeability and the finger-pressure operation by the protrusions (14) are obtained for improving health.

Granted: 2004-04-27
Abstract: Method and apparatus are provided for lining a pipe wherein a thermoplastic liner is initially formed in a cylindrical shape with a diameter slightly larger than the internal diameter of the pipe. The liner is temporarily deformed at an elevated temperature to a different cross-section, preferably U-shaped, to reduce its overall cross-sectional dimension to facilitate insertion into the pipe to be lined. The deformation occurs with substantially comparable elongation of the pipe lining along its opposite sides thereby precluding variations in wall thickness and stress in the pipe.      Once inserted, the liner is pressurized and reheated first to a temperature below its crystallization temperature to round the lining in the pipe and subsequently, further pressurized and reheated to a second temperature higher than the crystallization temperature to cause the liner to retain its original round shape.

Abstract: ADAPTABLE HUNTING STAND FOR LADDER-LIKE USE OR A-FRAME USE                   ABSTRACT         Interactive component parts for assembling an ATV-mounted hunting stand of either the "A"-frame type or tree-leaning type, or alternatively as a ground-standing tree-leaning hunting stand.  It includes a leveling seat platform, ladder elements, quick-grasping base connector assemblies, and a ground support.          The seat platform has angularly-adjustable sockets so sized as to fit onto the upper ends of ladder elements, whose lower ends may have sleeves to allow these ladder elements to be mounted atop other ladder elements.  Base connector sleeve assemblies allow ladder elements to be quickly and easily mounted on and demounted from rods attached to an ATV; they are free to pivot about these rods.  When such ladder elements are so mounted on an ATV as an A-frame hunting stand, changing the angularity of the seat sockets effects seat leveling.  For ground-standing ladder use, a broad ground support may be inserted into the lowest ladder element.
